To all whom it may concern:

Be it known that 1, CHARLES L. BAsrIAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Automatic Solution-Feeders for Carbonating or other Machines; of which the following is a specification.

This invention relates to carbonating apparatus; and its primary object is to provide an automatic feeder for supplying a mineral salt or other` solution to the carbonator.

A further object of the invention is to automatically feed a salt or other solution to the carbonator in measured quantity and at regular intervals, so that the solution will always be supplied to the carbonator in proper proportion to theliquid flowingtherein; and a further object is to operate the automatic solution-feeder from the pump-shaft of the vcarbonating apparatus, so that a measured quantity of the solution will be discharged into the suction-pipe of the pump at regular intervals to be carried into the carbonator by the liquid being pumped.

With these and other objects in view the invention consists in the novel devices and the peculiar construction and arrangement thereof hereinafter described, and illustrated in the accompanying drawings, in which- Figure 1 illustrates my invention applied to a carbonating apparatus, the latter being shown in broken lines. Fig. 2 is a side elevation of the pump and automatic solutionfeeder. Fig. 3 is an enlarged elevation of the solution-feeder. Fig. 4t is a central sectional view of the solution-feeder. Fig. 5 is a sectional View on the line 5 5 of Fig. 3. Figs. 6 and 7 are detail views showing the feeding device driven continuously by the pump-shaft.

It is unnecessary to describe the carbonating apparatus in detail, as it will be understood that my invention may be used in connection with any kind of carbonating` apparatus and in connection with any other` machine where it will be useful. The pump 10 is supported on a frame 11 and operated by a shaft 12, which carries a fly-wheel 13 at one 5o end and a loose pulley 14 and a tight pulley 15 at its other end, this pump-shaft being operated in a suitable manner by means ot' a Vbelt on the tight pulley.

' In the embodiment of the invention illustrated in the drawings the automatic solution-feeder is connected with the suctionpipe 16 of the pump and comprises a suitable tank 17 and a casing or barrel 18, provided with an upward hollow extension 19 and preferably cast integral with the suction-pipe. I prefer to construct the solution-tank of a glass cylinder 20, rigidly secu red to a base 21 by means of tie-rods 22, which pass through openings in lugs 23 around the base and corresponding lugs 24 on a top rim 25; but I do not limit myself to this particular construction, as it is obvious that other kinds of tanks may be used with equivalent results.

A feeding-plug 26 is arranged in the casing and provided with cups 27 atn intervalsin its periphery. The plug is provided at each end with a trunnion 28 to receive the disks 29 30, which'are secured in place against the. ends of the casing by nuts 31 on the trunnions to form a tight joint and are carried by the plug in its rotary movement. provided with longitudinal channels 32 between the cups, in which packing-bars 33 are arranged and pressed outwardly against the casing by springs 34.

The disk 30 is intermittently operated, like a star-wheel, and it carries anumber of studs v35, corresponding in number to the cups in the plug and located opposite thereto, these studs being provided with antifriction-rollers 36. A feeder-shaft 37 is journaled in suitable bearings,and it carries a tappet 38, which is arranged to engage the studs and impart an intermittent rotary motion to the plug, this movement being eected by means of the sprocket-chain 39, operating on the small sprocket 40, carried by the pump-shaft, and the large sprocket 41, carried by the feedershaft 37.

The construction of the solution-feeder is simple, and it is arranged tobe operated automatically to supply solution in regulated The plug is.

quantity-to the mixer 4.2, the operation of y lOO thereby automatically maintaining the relative proportion of the liquid and solution at all times. As the pump-shaft operates the feeder-shaft is rotated to bring the tappet into engagement with the studs of the disk 30, therebyimparting an intermittent rotary motion to the plug and discharging into the suction-pipe a measured quantity of solution at regularintervals. As the plug rotates each cup Will become lled with solution passing from the tank down through the passage 43 in the extension 19, and the spring-pressed packing-bars carried by the plug bear tightly against the inner wall of the casing and prevent the escape of the solution in the cups until the cup reaches the suction-pipe and empties therein. The liquid passing through the suction-pipe carries away all the solution from the cup then discharging and also thoroughly washes the cup during its rotary passage through the suction-pipe. I provide an opening 4:4 in the side of the casing above the suction-pipe to permit the escape of the liquid carried up by the cups from the suction-pipe, so that thc cups will always reach the solution-passage 43 empty and free from liquid.

I have shown and described the feederconnected with the suction-pipe of the pump; but it is obvious that it may be connected with the discharge-pipe of the pump or at other places without departing from the spirit and scope of the invention, and I therefore reserve the right to make all such changes and use the automatic solution-feeder with any other machine and forany otherpurpose within the scope of the invention.

The invention is designed primarily to be used for feeding a mineral-salt solution to carbonating apparatus in measured quantity and at regular intervals; but it is obvious that any kind of solution may be placed in the tank and fed by the device in the same manner and with equivalent results, and it will be understood, therefore, that I do not in any way limit the application of the invention by the illustration and the terms employed in the description to feeding a solution to a carbonating apparatus.

In Figs. l and 2 of the drawings I have shown the feeder-shaft geared to rotate once to two rotations of the pump-shaft, so that a cup of solution will be discharged into the suction-pipe at two complete operations of the pump; but this gearing may be changed and the number of cups may be increased or decreased to correspondingly change the feeding of the solution.

Instead of operating the feeder intermittently, as hereinbefore described, I may drive the plug continuously by providing it with a feeder-shaft 37', on which the sprocket 41 is mounted, as shown in Figs. 6 and 7. By this construction the plug will be continuously operated with the pump-shaft, and the sprockets may be constructed so that the pumpshaft Will revolve four times to each single revolution of the feeder-shaft, or the plug may be provided with a less number of cups.

With these and other ends in view, what I claim, and desire to secure by Letters Patent, 1s-

1. A solution-feeder for carbonating and other apparatus, comprising a tank, a casing connected with said tank, a device arranged in said casing and provided With cups to receive solution from 4the tank, packing-bars carried by said device between the cups, and means for imparting a rotary motion to said device to feed solution from the tank in measured quantity and at regular intervals.

2. The combination With a pump and a suction-pipe therefor of a tank, a casing communicating with the suction-pipe and the tank, a feeding device arranged in said casing and working partly in the pipe and provided with cups to receive solution from the tank and discharge same into the suction-pipe, said casing being provided with an opening in its side to permit the escape ot' liquid carried up by the cups from the suction-pipe and means for operating the pump and imparting an intermittent rotary motion to said feeding device.
